Show me your bielefelder crosses.

One of my boys was a ((Biel x JG) x (JG x BA)). He died a few weeks ago, and unfortunately I can't find any pictures of him. I have a new set of chicks, of which 3 appear to be his, but I noticed that one of the older pullets also has something that looks like messy barring, which would mean he is her father. Her mother was Marans, so she is either (((JG x RIR) x RIR) x Marans), or ((Biel x JG) x (JG x BA)) x Marans).

The third picture shows it most clearly. I can't see where else this patterning may be coming from. She just seems to have random feathers with a barring pattern.

What chance that she's a Biel mix?

That isn’t barring, barring is white bars

The barring gene makes white lines across the feathers.
Certain other genes or combinations of genes can cause lines of black and brown with no white, like what I see in your picture.

I don't see anything that would prove her to be from one rooster or from the other rooster.
